This invention relates to an improved methd of printing or placing watersoluble dyestuffs on a paper base, that are capable of being transferredto biscuit ware, water ab- 6 sorbent wallboards, fabrics, etc. withoutbleeding around the edges.

In the accompanying drawings Fig. 1 is a plan view of a transfer sheetembodying my invention, showing a multi-col- 10 ored design bordered bya layer of bleeding preventive substance; and

Fig. 2 is an enlarged transverse vertical section taken on line 22 ofFig. 1.

It is known to those skilled in the art that when water solubledyestuffs are printed or applied in a suitable medium to a paper. base,to be afterwards transferred to material, and the colors placed adjacentto each other, as in a multi-color design or printing, that such adesign can be transferred to a wetted surface by pressure or by wettingthe same from the back and the colors adjacent to each other will notrun or bleed, but there will be a bleeding on the outside edges.

This is overcome in the present invention by printing or applying aborder of a water soluble gum, or equivalent material closely around allthe outside edges of the design or marking placed upon the transfersheet. For simplicity in manufacture this can be first applied orprinted on the paper base before the design or marking consisting of oneor more colors is placed thereon. To carry out my invention, I print orapply to a paper base as required to form a border to the design ormarking, a coating of a water soluble gum in solution as dextrine, madefrom tapi oca or other starch producing dextrines having a highviscosity and which leaves a continuous film upon drying, and is readilysoluble when brought into contact with a wetted surface to be marked ordecorated, thus forming in or on the wetted material a solution of highviscosity into which the adjacent dyestuif would not perceptiblypenetrate.

While I have described my invention as preferably employed with watersoluble dyes and a water soluble gum, it will be understood that theprinciples of the invention are broadlyb applicable to any designtransfer having coloring matter which may bleed around the edges of thedesign.

This is a quick method for transferring and the transf'er'need only bepressed on providing moisture is applied to the surface to be 58 markedor if a transfer be made on a moderately porous paper the water can beapplied from the back, providing said paper does not readily absorb thedye,--such as a mimeograph paper printed with basic colors 00 insolution, or porous paper otherwise treated to resist the particularkind of dyestufl used.

Instead of dextrine gum arabic can be employed or any of the gumssoluble in cold water.

Having thus described my invention what lclaim and desire to secure byLetters Patent is:

1. A methed of making a'transfer which consists in applying to a base adesign in one or more colors composed of an ink containing water-solubledyestuff and applying a border of water-soluble gum capable of forming asolution of high viscosity when wetted and placed in contact with asurface to be marked or decorated.

2. A method of making a transfer which consistsin applying to a base adesign in one or more colors composed of an ink containing water-solubledyestulf in solution and applying a colorless border of water-solublegum capable of forming a solution of high viscosity when wetted andplaced in contact with a surface to be marked or decorated, said bordersurrounding and being contiguous to the edges of the design.

3. A method of making a transfer which consists in applying to a base adesign in one or more colors composed of an ink containing Water-solubledyestuff and surrounding the design with a colorless border ofwater-soluble gum adapted to form a solution of high viscosity whenwetted and placed in contact with a surface to be marked or decoratedwhereby the design colors are prevented from bleeding at the borders ofthe design.

4. A transfer sheet comprising a base having a design in one or morecolors imprinted thereon with sm ink containing water-soluble dyestufi'and a layer ofwater-soluble gum bordering the deslgn.

5'. A transfer sheet comprising a base having a design in one ormorecolors imprinted thereon with an ink containing water-soluble dyestufland a water-soluble agent for preventing blee'ding or running of thedyestulf when moistened bordering the design.

6. A transfer sheet comprising a. base having a design in one or morecolors imprinted thereon with an ink containing water-soluble dyestuffin solution and a layer of watersoluble gum capable of forming'a highviscosity solution when moistened bordering the design for preventingspreading of the dyestuif during the transfer operation.

7. A transfer sheet comprising a base having a design in one or morecolors imprinted thereon with an ink containing water-soluble dyestufi'in solution and a layer of colorless water-soluble gum capableof forminga high viscosity solution when moistened surrounding the design forpreventin spreading of the dyestuff during the trans er operation. V

8. A transfer sheet comprising a base havmg a designin one or morecolors imprmted thereon with an ink containing water-soluble dyestufl"in solution and a layer of watersolublegum capable of forming a highviscosity solution when moistened surrounding and contiguous to thedesign for preventing spreading of the dyestufi during the transferoperation.

9. A transfer sheet comprising a paper base having a design in one ormore colors imprinted thereon with an ink containing soluble dyestufi'sin solution and a border of.

colorless Water-soluble gum capable of forming a high viscosity solutionwhen wetted I on the back and pressed into contact with a surface to bemarked or decorated, said border substantially surrounding the designand being contiguous therewith whereby the dyestufls are prevented fromrunning or bleeding at the edges of the design.

10. A transfer sheet comprising a base having a design in one or-morecolors imprinted thereon with'an ink containing water-soluble dyestufl'and a layer of gum arabic bordering the design.

In testimonywhereof I afiix my signature.
